Sorry, Corky, but your "turnbuckle bureaucrat" has been long retired and isprobably dead & buried! (must have worked in the Civil Aeronautics Boardunder Roosevelt!! ;-)I checked thru my old copy of CAM 18 for the "3 threads" (it's there) & inthe 1958 Amateur Builders Manual (early EAA pub.) it has a drawing showing 3threads out to 4 threads in as a range for adjustment. That gives us arange of 7/16" on the 1600# turnbuckles -- enough to adjust your elevatortrailing edge + or - 1" from the walking beam connection.another Mike C. -- (waiting for my wood to arrive!!)Pretty Prairie, KS________________________________________________________________________________

Mine held, but I left some extra length at the front and NAILED the front ofthe longeron to the work table while I was bending it. There was probably100 lbs of force trying to make the front spring back out and the cleatsthat I used for the rest of the fuselage just didn't work.Gene HubbardSan Diego-----Original Message-----

if using stranded cable you can adjust (tighten) brace cables with a twist or twoand eliminate turnbuckles alltogether saves weight and money especially ontailfeathers Its done on Roger Manns designs with the same tail surface areaand speeds as the pietenpolregards Norman________________________________________________________________________________

Doc,I just went to a local ships chandler near Melbourne. Even some BearingsWarehouse's have them.I bought a load of cable shackles. I needed to re-drill the hole for aclevis pin and bend the ends together a bit. Look good and are strong.CheersPeterWonthaggi, Australiahttp://www.cpc-world.com-----Original Message-----

Hi DickThanks for the quick response. I have studied the pictures in the Aircraft Spruce catalog and cannot see any way to run the wire through the pin end to turn it back on the turnbuckle, whithout going around the pin itself, which looks to me to be unacceptable. I guess I will step back and start over with a fork end arrangement to remove the problem. This is connecting the rudder cables to the rudder horns. through flat metal links, because when putting the fork end of a turnbuckle directly to the rudder, I found that I could only get a few degrees of deflection of the rudder before the fork would jam in the horn. This would also possibly damage the safety wire over time.I am still curious if there is a proper way to do this. I think the fork end is a better arrangement anyway and will go that route.Don L________________________________________________________________________________Date: Mon, 18 Oct 2010 09:22:50 -0700 (PDT)

Hi John,There is no solo requirement to get your tailwheel endorsement. Rather, as Andrew cited, you must be signed off (get an endorsement) from a CFI showing you are proficient in the operations he listed. You do not need a medical to train, ie get the dual instruction. Obviously you can not solo the Citabria once you have the endorsement because it is not a LS.As an Instructor I would give you the sign-off without your medical, after explaining to you that you could not act as PIC in a non-LS aircraft because you lacked the medical. However, you are good to go in a LS.Jim----- Original Message -----

Re: Pietenpol-List: turnbuckles
Original Posted By: Jack
Early on in my Piet build I bought a large number of used turnbuckles at Oshkosh. A couple years ago I took one of the end forks with me to Oshkosh to be sure and get the correct size pins for the fork end. Now that I am assembling the tail pieces I find I have misplaced the fork end to one of the turnbuckles. I located a supple of used turnbuckles locally but can=99t find one of the same thread pitch. I found one of the same diameter but only about 4 threads will fit into the barrel. Under a microscope I count 30 threads per inch on the type fork I need to replace. The used one I found has 32 threads per inch as does the forks available from Aircraft Spruce. Is it possible the used turnbuckles I got years ago at Oshkosh are a military spec which is different than the thread spec currently used on civilian aircraft? I will be able to replace the entire turnbuckle unit but I am curious about the 2 threads per inch difference in the forks. Anybody have any explanation?Ralph in SD________________________________________________________________________________Subject: Re: Pietenpol-List: turnbuckles
Early on in my Piet build I bought a large number of used turnbuckles at Oshkosh. A couple years ago I took one of the end forks with me to Oshkosh to be sure and get the correct size pins for the fork end. Now that I am assembling the tail pieces I find I have misplaced the fork end to one of the turnbuckles. I located a supple of used turnbuckles locally but can=99t find one of the same thread pitch. I found one of the same diameter but only about 4 threads will fit into the barrel. Under a microscope I count 30 threads per inch on the type fork I need to replace. The used one I found has 32 threads per inch as does the forks available from Aircraft Spruce. Is it possible the used turnbuckles I got years ago at Oshkosh are a military spec which is different than the thread spec currently used on civilian aircraft? I will be able to replace the entire turnbuckle unit but I am curious about the 2 threads per inch difference in the forks.

Here in Oregon the car gas has ethanol in it. This ethanol is mixed in as the truck is loaded with fuel at the distributor. If you have a large tank (300 gal.) they will deliver ethanol free gas at about the same as the local stations are charging.
